Abstract

The invention discloses a data quality management method and a data quality management system. The data quality management method comprises the following steps: managing a quality knowledge library; analyzing the data quality characteristics, and presetting a quality problem domain, a quality dimension domain, a quality rule domain and a quality standard domain; collecting quality information: selecting the quality dimension and the quality rules required by a user from the quality knowledge library, and extracting a data set meeting the user requirements from the original data sets; evaluating the data quality: evaluating the data quality according to the collected quality information, and generating and submitting a data quality report to the user or a quality manager according to the quality problem domain and the quality standard domain in the quality knowledge library; and improving the data quality: correcting the data quality problem detected in the evaluation of the data quality for improvement. The data quality management method and the data quality management system are applied to monitoring, evaluating and continuously improving the data quality in the whole hydrology industry based on the whole data processing procedure of the hydrology industry.

Description

technical field [0001] The invention relates to a data quality management method and system, in particular to a data quality management method and system in the hydrological industry. Background technique [0002] The national hydrological database is an important basic information base of national conditions and a strategic information resource base. It is the basis for decision-making of all water affairs activities in national economic construction and social development. It is also the main body of the hydrological industry serving the fields of society, economy, environment, ecology, and national defense. information products. For many years, due to the lack of a unified data storage specification, the storage forms of hydrological data in various places are different, and the status quo of hydrological databases is far from meeting the needs of social development. Therefore, it is necessary to speed up the construction of the national hydrological database to better p...
